Q2 A single stage nozzled axial flow gas turbine operates with 1000 K total inlet temperature and 4.8 bar inlet total pressure with 12 kg/s mass flow rate. The axial velocity throughout the stage is constant at 220 m/s and the blade speed is 350 m/s. The nozzle exit and the rotor exit angles are 65° and 7° respectively. The static pressure at the exit of the stage is 2.5 bar. Assuming equal inlet and exit absolute flow velocities, determine: (i) relative flow angle at rotor inlet; (ii) relative velocity at stage inlet; (iii) relative flow angle at rotor exit; (iv) relative velocity at stage exit; (v) absolute flow velocity; (vi) degree of reaction; and (vii) specific power output of the turbine
